Class Collection<T, V>

Every record, deduplicated by id, in first-seen order.

Number of distinct records.

Look up by exact id.

Look up by exact id within a faction. Use this when an id is shared across factions (e.g. chaos-land-raider lives under five Chaos factions) and a faction context is known — get would return whichever copy was registered first, which may belong to the wrong faction. Returns undefined when no record with that id belongs to factionId.

Whether a record with this exact id exists.

Find one record by id or name. Name matching is diacritic- and punctuation-insensitive (see normalizeName), trying, in order: exact id → exact normalized name → normalized-name substring. Returns the first match; names can repeat across factions, so use findAll or byFaction when a query may be ambiguous.

All records matching a query, by the same rules as find. An exact id match returns just that record; otherwise every normalized-name-exact match is returned, falling back to every normalized-name-substring match. Useful to surface (rather than silently collapse) names shared across factions.

All records belonging to a faction id (empty if the type has no faction).
